Set ceph-public-address with monitor-hosts config

charms capable of relating to ceph build the list of monitor hosts
from the ceph-public-address in the relation data or simply using the
private-address field provided by juju.

This patch populates ceph-public-address in the relations with the
list of monitor hosts provided in the configuration, so clients connect
directly to the non juju managed ceph and not to ceph-proxy IP.

Closes-Bug: #1642430
